Key Takeaways
  • • Mercuria Energy Group alleges the Baltic Exchange kept publishing a disputed benchmark oil tanker rate despite distortions from the Iran war, because it feared losing business to a competitor.
  • • Mercuria's lawyers argue the Baltic Exchange should have suspended the benchmark after exports through the Strait of Hormuz were disrupted by the conflict between the US, Israel and Iran.
  • • The Baltic Exchange contests the claim and denies breaching its duties as a benchmark administrator.
  • • The case is being heard at a London trial, with the outcome likely to bear on benchmark governance and administrator obligations in physical commodity markets.
Summary
Commodity trader Mercuria Energy Group has accused the Baltic Exchange of continuing to publish the world's benchmark oil tanker rate even though the Iran war had distorted it, according to Bloomberg. Mercuria alleges the exchange was motivated by fear of losing business to a competitor.

Lawyers for Mercuria opened the case at a trial in London. They contend that the Baltic Exchange should have suspended the benchmark rate once exports through the Strait of Hormuz were severely constrained by the conflict between the United States, Israel and Iran. The disruption to Hormuz flows is central to Mercuria's argument that the published rate no longer reflected market conditions.

The Baltic Exchange is contesting the claim. It denies breaching its duties as a benchmark administrator, and the court will weigh whether its decision to maintain the rate met those obligations.

The dispute matters beyond the two parties. Tanker benchmarks are widely used to price freight and related contracts, so questions about whether an administrator should suspend a rate during a supply shock go to the reliability of published benchmarks for institutional counterparties. The primary source does not disclose the rate level, the quantum of any damages sought, or the timetable for a verdict.
